Vernon Hershberger, of Loganville, has been charged with operating a dairy farm, dairy plant and retail food establishment without appropriate licenses. Hershberger contends he has been targeted for selling unpasteurized milk, which is illegal in Wisconsin in most cases.

But state officials say raw milk isn't the issue -- even farmers selling pasteurized milk need the right licenses.

Hershberger's supporters have rented a theater across from the courthouse in Baraboo to monitor the trial and hold a rally.
